' 11.01 m. ,(o1.'139--1ss) the front of the loom, which is toward the right The present invention pertains to yielding reed mechanisms for fly shuttle looms and more particularly to the filter and fliter controlling devices of such mechanisms.

In looms of the type to which my invention applies, a reciprocating lay, including a lay beam, carries a reed which is rearwardly yieldable relative to the lay beam and which is yieldingly urged forwardly by spring-actuated bolts or rods. 10 These spring-actuated rods act on a fliter, so-

called, which may support the lower reed rib.

Adjusting means are usually provided, for adjusting the spring tension on the rods. The filter must be freed from the action of these rods on 15 several occasions, such as whenever it is desired to test the freedom of the swinging movement of the reed or when the reed is to be removed from the loom for purposes of replenishing the warp supply.

Prior yielding reed mechanisms of the type above described were so constructed that the filter could be freed from the action of the springactuated rods only by removing the actuating springs and the adjusting means therefor. Such removal of the springs and adjusting means is inconvenient, time-consuming, and requires that the spring tension be readjusted before the loom is again put in operation.

I propose to provide a yielding reed mechanism including the lay beam, a rearwardly yieldable fliter, and a spring-actuated rod for yieldingly urging the filter forwardly, which filter and rod shall be so constructed and arranged that the rod can be quickly and easily disengaged from 35 the fliter, and which shall not be subject to the above-mentioned disadvantages of prior constructions.

The foregoing and other objects of the invention are accomplished in the construction illustrated on the accompanying drawing, of which:

Fig. 1 is a view in rear elevation of part of a lay having the preferred embodiment of my invention applied thereto; and

Fig. 2 is a View in cross-section taken approxi- 5 mately on line 2-2 of Fig. 1.

The drawing shows part of a lay having my improved yielding reed mechanism, the other mechanisms of the loom (not shown) being of any suitable usual construction and forming no part of the present invention. The lay construction shown on the drawing includes a lay beam I which is supported on lay swords such as the lay sword 2. The lay swords are of usual construction and are pivoted in the usual manner so that the lay may reciprocate-toward and from on Fig. 2. The lay carries a reed 3 for beating the filling into place, the reed being movable rearwardly relative to the lay beam.

In the particular embodiment shown on the drawing, the reed is fixed in a movable reed frame. This frame may include the usual hand rail 4 and a bar 5, commonly called a filter. The hand rail and bottom bar are rigidly connected in spaced relation by end brackets such as the bracket 6. The top reed rib 'I' is received in a longitudinal groove in the under side of the hand rail 4, and the bottom reed rib 8 is received in a groove in the top of the filter 5. The end brackets of the reed frame are pivoted on horizontal pivots, such as bolt 9, so that the reed frame and reed may swing forwardly and rearwardly relative to the lay beam. Forward movement of the reed is limited by adjustable stop screws I which are engaged by the fliter when the reed is forward.

A bolt I I and spring I2 comprises part of means for holding the reed against rearward movement during the time the lay is back and the shuttle is in flight. Such means is not active when the lay is forward and it is not of the present invention. For a complete disclosure of the same, reference may be had to patent to E. C. Nichols, No. 2,087,859, granted July 20, 1937.

The present invention provides a novel means for yieldingly resisting rearward movement of the reed frame, the preferred embodiment of which includes a series of rods and springs. The drawing shows only one such rod I3 and spring I4, the other rods and springs of the series being spaced along the lay and being of exactly the same construction as those shown. The rod I 3 shown extends forwardly and rearwardly of the loom below the fliter 5 and is supported by the lay beam I for both rotating and axial sliding movement. To this end. the rod I3 may extend through a horizontal opening I5 in the lay beam which opening forms a bearing for the rod.

The rearward end of the rod I3 has a lateral projection I6 which engages behind the fliter 5. The spring I4 is arranged to yieldingly urge the rod I 3 forwardly, so that the spring and rod yieldingly resist rearward movement of the filter and reed. As shown, the spring I4 is a helical coiled spring which is positioned on the forward end of the rod and is compressed between the lay beam and adjusting nuts I! which are threaded onto the rod. It will be apparent that by adjusting the nuts I! the strength of the resistance to rearward movement of the fiiter may be varied, to

adapt the mechanism to different weaving conditions.

The rod I3 is rotatable in its bearing IE but is normally held against rotation, to hold the projection l6 in engagement with the fliter. In accordance with the present invention, such holding means is manually releasable, to permit the rod to be manually rotated whenever it is desired to free the fiiter from the action of the spring [4. In the embodiment shown, the projection 16 is formed by bending the rearward end of the rod I3 upwardly, and the aforesaid holding means is formed by bending the projection forwardly and inserting the forwardly extending end l8 into a hole I9 which extends forwardly from the back of the fiiter.

During the normal operation of the loom, the end I8 will be seated in the hole i9 as shown, and the projection 16 is thereby held in engagement with the fiiter. However, with this construction the reed and fiiter may be freed from the action of the spring i4 merely by pushing or sliding the rod l3 rearwardly, to withdraw the end l8 from the hole [9, and then rotating the rod. This dis engagement of the projection I6 from the fliter is effected quickly and easily and without disturbing the adjustment of the nuts I1.

Having fully disclosed the preferred embodiment of my invention, I claim:

In a yielding reed mechanism for looms, the combination of a lay beam and rearwardly yieldable fiiter, with manually releasable means for yieldingly resisting rearward movement of said fiiter, said means comprising a rod extending forwardly and rearwardly below said filter, the rearward end of said rod being bent upwardly and then forwardly and inserted into a hole extending forwardly from the back of said fiiter, said rod being supported for rearward sliding movement to withdraw said end from said hole and being rotatable out of engagement with said fiiter, and a coiled spring on the forward end of said rod for yieldingly urging the rod forwardly.
